Apple currently has more vehicles registered than Waymo, which has 51, in agreement with the California DMV. General Motor’s Cruise, however, results the pack with 104 vehicles. In total, the DMV has provided to 53 companies permits for self-driving vehicles that include security drivers, resulting in a total of 409 vehicles and 1,573 security drivers.

To be clear, the companies listed above only have permits to exam self-driving vehicles with safety drivers on board. As of now, the DMV has not issued any permits for complete driverless testing. In order to conduct driverless testing, companies must have previously tested the vehicles in controlled conditions.

The vehicles must also, among many other things, satisfy the definition of an SAE Level 4 or 5 vehicle. The DMV is currently reviewing two driverless testing permit applications, a DMV spokesperson told TechCrunch.
